Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, in particular to an automatic packaging device for steel furniture. Background Art

[0002] Steel furniture is a type of furniture made of steel as the main material. It has been increasingly used in recent years due to its advantages such as good durability, high environmental protection, high safety and high space utilization.

[0003] During the transportation of steel furniture, due to its large size after assembly, it will take up more transportation space. Excessive transportation space not only means higher transportation costs, but also may exist potential transportation loss risks. Therefore, in order to improve efficiency, when packing steel furniture, it is usually split into different parts and then packaged separately.

[0004] In the process of packaging steel furniture parts, a packaging machine is needed. In the related technology, Chinese patent application CN117022748A discloses an automatic packaging machine. During the use of the automatic packaging machine, when the strapping mechanism completes the strapping of the box at a placement angle and the box needs to be cross-strapped, the two semicircular frames and rollers can be driven to rise by the first driving device. Since the top of the roller is higher than the top of the horizontal conveying mechanism after it is raised, the lifting and rotating mechanism lifts the box, and all the rollers surround to form a circular conveying track. The strapping and placement angle of the box can be adjusted by the rolling of the rollers. After the angle adjustment is completed, the two semicircular frames and rollers are driven to be lowered by the first driving device, and the strapping mechanism is used for strapping.

[0005] Although the above-mentioned automatic packaging machine is capable of bundling steel furniture parts, it is found in actual use that due to the fixed size of the gantry, the timing of tightening the strapping belt is different when packaging steel furniture parts of different sizes. As a result, when bundling smaller steel furniture parts, the strapping belt is often prone to deflection and cannot be tightly tightened, which not only affects the bundling effect of the steel furniture parts, but also easily causes rework, affecting the bundling efficiency of the steel furniture parts. Summary of the invention

[0006] Based on this, it is necessary to provide an automatic packaging device for steel furniture to address the problems of poor bundling effect and low bundling efficiency in the current packaging process of steel furniture parts.

[0007] The above purpose is achieved through the following technical solutions: An automatic packaging device for steel furniture, the automatic packaging device for steel furniture comprising a strapping machine body, the strapping machine body having a strapping platform, the strapping platform being provided with a strapping station and a gantry, the strapping station being configured to receive materials to be packaged; a first belt groove and a guide portion being provided on the inner side wall of the gantry, the first belt groove having the same shape as that of the gantry, and having a strapping belt inserted therein when in use; the guide portion being configured to extend the guiding distance of the first belt groove for the strapping belt.

[0008] Further, the guide portion is configured to be movable toward or away from the strapping station.

[0009] Furthermore, the automatic packaging device for steel furniture also includes a transfer component, which is configured to be able to transfer the strapping belt to a connection point beyond the guide portion and the gantry.

[0010] Furthermore, the transfer assembly includes a guide portion, a force generating portion and three elastic telescopic strips, the three elastic telescopic strips are all inserted in parallel in the first belt groove and are respectively located at the three inner side walls of the gantry; the elastic telescopic strip is arranged as a U-shaped structure with its opening facing the bundling station, the two parallel parts of the elastic telescopic strip are arranged as a wavy structure, and the relatively concave positions on the parallel parts are provided with guide rods, the guide rods and the elastic telescopic strips are arranged in parallel; the guide portion is configured to guide the guide rod to slide along the groove depth direction of the first belt groove; the force generating portion is configured to generate a force between the guide rod and the strapping belt; when in use, the strapping belt passes through the elastic telescopic strip in parallel, and can be clamped by the guide rod and moved in a direction close to the strapping station under the action of the force.

[0011] Furthermore, the acting force is set to be a magnetic force.

[0012] Furthermore, the acting force is set to be suction.

[0013] Furthermore, the guide portion includes three guide rail groups, each of which includes two pairs of guide rails. The two pairs of guide rails of the same guide rail group extend along the groove depth direction of the first belt groove, and the two guide rails of the same pair are respectively arranged at both ends of the same elastic telescopic strip; the two ends of the guide rod are respectively slidably inserted into the two guide rails of the same pair.

[0014] Furthermore, the automatic packaging device for steel furniture also includes a driving member, which is configured to provide a driving force for moving the guiding part.

[0015] Furthermore, the guide portion includes three pairs of guide plates, which are respectively inserted on the three inner walls of the gantry, and the two guide plates of the same pair are parallel and spaced apart on both sides of the first belt groove, and form a guide channel, which is connected to the first belt groove.

[0016] Furthermore, the material of the strapping belt is set to be nylon.

[0017] The beneficial effects of the present invention are: During use of the automatic packaging device for steel furniture disclosed by the present invention, the material to be packaged is first placed at the bundling station, and then the bundling machine is started to bundle the material to be packaged; during the bundling process, since the guiding part extends the guiding distance of the first belt groove to the bundling belt, the probability of the bundling belt being tilted can be reduced by reducing the time that the bundling belt is in a completely free state, so that the bundling belt will not be too deflected during the contraction process, thereby ensuring the bundling effect and reducing the probability of rework.

[0018] Furthermore, by arranging the guide part to be able to move toward or away from the bundling station, during use, when the size of the material to be packaged is large, the guide part can not only clamp and position the material to be packaged, but also extend the guiding distance of the first belt groove to the bundling belt, thereby further improving the bundling effect; when the size of the material to be packaged is small, the guide part can extend the guiding distance of the first belt groove to the bundling belt, thereby ensuring the bundling effect and increasing the bundling range of the automatic packaging device for steel furniture.

[0019] Furthermore, a transfer assembly is provided so that during use, when a part of the guide portion is inserted into the gantry and the other part is inserted into the first belt groove, the guide portion and the first belt groove together form a stepped structure. When the strapping strap contracts, the transfer assembly can transfer the strapping strap to a connection point that passes over the guide portion and the gantry, thereby preventing the strapping strap from being in a completely free state and being caught by the stepped structure, thereby avoiding affecting the strapping process. When the guide portion is away from the first belt groove, when the strapping strap contracts, the transfer assembly can transfer the strapping strap to a connection point that passes over the guide portion and the gantry, thereby minimizing the time that the strapping strap is in a completely free state, thereby reducing the probability of the strapping strap tilting.

[0025] like Figures 1 to 7 As shown, the automatic packaging device for steel furniture provided in an embodiment of the present invention is used for bundling parts of steel furniture, and is configured to include a strapping machine body 1, the strapping machine body 1 has a strapping platform 101, and the strapping platform 101 is provided with a strapping station 102 and a gantry 103, the strapping station 102 is configured to receive materials to be packaged; a first belt groove 1031 and a guide portion 2 are provided on the inner side wall of the gantry 103, the shape of the first belt groove 1031 is the same as that of the gantry 103, and a strapping belt 5 is inserted therein when in use; the guide portion 2 is configured to extend the guiding distance of the first belt groove 1031 to the strapping belt 5.

[0026] Specifically in this embodiment, Figure 1 As shown, the strapping platform 101 is configured as a flat plate structure and is installed on the top of the strapping machine body 1, and the plate surface is arranged horizontally; the gantry 103 is configured to be composed of a crossbeam and two vertical beams, wherein the crossbeam is arranged horizontally during installation and is suspended above the top of the strapping platform 101, and the vertical beam is arranged vertically during installation, and the top ends of the two vertical beams are respectively arranged vertically at the bottom of both ends of the crossbeam, and the bottom ends are both arranged vertically at the top of the strapping platform 101; the strapping station 102 is located directly below the crossbeam.

[0027] The first belt groove 1031 is configured to consist of a transverse groove section and two vertical groove sections, wherein the transverse groove section is opened in parallel at the bottom of the cross beam, and the two vertical groove sections are opened in parallel on the two opposite inner side walls of the two vertical beams, and the two ends of the transverse groove section are respectively vertically connected with the two vertical groove sections; when the strapping strap 5 is located inside the first belt groove 1031, it is limited by the groove width of the first belt groove 1031, so that the strapping strap 5 will not be completely in a free state. At this time, the groove depth of the first belt groove 1031 is the guiding distance of the first belt groove 1031 to the strapping strap 5; and when the strapping strap 5 is separated from the first belt groove 1031, it is not limited by the groove width of the first belt groove 1031, so that the strapping strap 5 is completely in a free state, which may cause tilting, and then the strapping effect is deteriorated.

[0028] Therefore, the guide portion 2 can extend the guiding distance of the first belt groove 1031 for the strapping belt 5 by deepening the groove depth of the first belt groove 1031 , thereby reducing the time that the strapping belt 5 is completely in a free state.

[0029] During use, firstly, the parts of the steel furniture are placed at the bundling station 102, and then the bundling machine body 1 is started to bundle the parts of the steel furniture.

[0030] During the bundling process, the strapping machine body 1 first drives the strapping belt 5 to pass through the first belt groove 1031 to form an annular strapping structure, and then drives the strapping belt 5 to be tightened, so that the strapping structure gradually shrinks and gradually tightens the parts of the steel furniture. In this process, since the guide part 2 extends the guiding distance of the first belt groove 1031 for the strapping belt 5, the probability of the strapping belt 5 being tilted can be reduced by reducing the time that the strapping belt 5 is in a completely free state, so that the strapping belt 5 will not be too deflected during the contraction process, thereby ensuring the strapping effect and reducing the probability of rework.

[0031] After the strapping belt 5 has tightly bound the parts of the steel furniture, the strapping machine body 1 first bonds the two ends of the strapping structure, and then cuts off the strapping structure and the strapping belt 5, thereby completing the bundling of the parts of the steel furniture.

[0032] In a further embodiment, in order to increase the bundling range of the automatic packaging device for steel furniture, the guide portion 2 is configured to be able to move toward or away from the bundling station 102 .

[0033] During use, when the size of the parts of the steel furniture is large, the guide part 2 can not only clamp and position the parts of the steel furniture, but also extend the guiding distance of the first belt groove 1031 to the strapping belt 5, thereby further improving the strapping effect; when the size of the parts of the steel furniture is small, the guide part 2 can extend the guiding distance of the first belt groove 1031 to the strapping belt 5, thereby both ensuring the strapping effect and increasing the strapping range.

[0034] In a further embodiment, the automatic packaging device for steel furniture is configured to further include a driving member, and the driving member is configured to provide a driving force for moving the guide part 2 .

[0035] Specifically in this embodiment, the driving member can be configured as a driving cylinder 4 and is disposed on the gantry 103 . The output shaft of the driving cylinder 4 is disposed toward the strapping station 102 and is fixedly connected to the guide portion 301 .

[0036] It can be understood that the driving cylinder 4 can be configured as any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0037] In other embodiments, the guide portion 2 can be configured to include three pairs of guide plates 201, which are respectively inserted into the three inner walls of the gantry 103, and the two guide plates 201 of the same pair are parallel and spaced apart on both sides of the first belt groove 1031, and a guide channel 202 is formed, which is connected to the first belt groove 1031.

[0038] Specifically in this embodiment, Figure 4 As shown, one pair of guide plates 201 is inserted on the horizontal beam, and the plate surface is arranged vertically. The two guide plates 201 of the pair are arranged at intervals on both sides of the horizontal slot section, and the guide channel 202 formed by the two guide plates 201 of the pair is connected to the horizontal slot section, so as to extend the guiding distance of the horizontal slot section for the strapping strap 5; the other two pairs of guide plates 201 are respectively inserted on the inner side walls of the two vertical beams, and the plate surface is arranged vertically. The two guide plates 201 of the same pair are arranged at intervals on both sides of the vertical slot section, and the guide channel 202 formed by the two guide plates 201 of the same pair is connected to the vertical slot section, so as to extend the guiding distance of the vertical slot section for the strapping strap 5, thereby extending the guiding distance of the first belt groove 1031 for the strapping strap 5.

[0039] In a further embodiment, in order to facilitate the provision of driving force for the movement of three pairs of guide plates 201, the number of drive cylinders 4 can be set to three, and they are respectively arranged on the top of the horizontal beam and the outer walls of the two vertical beams. The output shaft of the drive cylinder 4 faces the bundling station 102 and is arranged on the two guide plates 201 of the same pair.

[0040] In other embodiments, when the guide portion 2 is configured to be able to move toward or away from the strapping station 102, and the guide portion 2 is configured to include three pairs of guide plates 201, the guide plates 201 have two installation methods, one of which is to insert a portion into the gantry 103 and the other portion into the first belt groove 1031, and the other is to insert the entirety into the gantry 103 and spaced apart from the first belt groove 1031. In the former installation case, the guide plate 201 will form a side wall of the first belt groove 1031 together with the side wall of the first belt groove 1031. The stepped structure makes it easy for the strapping strap 5 to be caught by the stepped structure when it shrinks, resulting in damage. In the latter installation situation, since the two guide plates 201 of the same pair have a wider interval than the first belt groove 1031, the strapping strap 5 is less restricted, which in turn leads to a poor guiding effect on the strapping strap 5. To solve this problem, the automatic packaging device for steel furniture also includes a transfer component 3, which is configured to be able to transfer the strapping strap 5 to a connection point beyond the guide portion 2 and the gantry 103.

[0041] When a part of the guide plate 201 is inserted into the gantry 103 and the other part is inserted into the first belt groove 1031, during the contraction of the strapping belt 5, the strapping belt 5 can be transferred to the connection between the guide part 2 and the gantry 103 by the transfer component 3, thereby preventing the strapping belt 5 from being in a completely free state and being caught by the stepped structure, thereby avoiding affecting the strapping process; and when the guide plate 201 is away from the first belt groove 1031, during the contraction of the strapping belt 5, the strapping belt 5 can be transferred to the connection between the guide part 2 and the gantry 103 by the transfer component 3, thereby minimizing the time that the strapping belt 5 is in a completely free state, which is conducive to reducing the probability of the strapping belt 5 tilting.

[0042] In a further embodiment, the transfer assembly 3 is configured to include a guide portion 301, a force generating portion and three elastic telescopic strips 302, the three elastic telescopic strips 302 are all inserted in parallel in the first belt groove 1031, and are respectively located at the three inner side walls of the gantry 103; the elastic telescopic strip 302 is configured to be a U-shaped structure, and the opening is facing the strapping station 102, the two parallel parts of the elastic telescopic strip 302 are both configured to be a wavy structure, and the relatively concave positions on the parallel parts are both provided with guide rods 303, and the guide rods 303 and the elastic telescopic strips 302 are arranged in parallel; the guide portion 301 is configured to guide the guide rod 303 to slide along the groove depth direction of the first belt groove 1031; the force generating portion is configured to generate a force between the guide rod 303 and the strapping belt 5; when in use, the strapping belt 5 passes through the elastic telescopic strip 302 in parallel, and can be clamped by the guide rod 303 under the action of the force and move in a direction close to the strapping station 102.

[0043] Specifically in this embodiment, Figure 3 As shown, one of the elastic expansion strips 302 is inserted in parallel in the horizontal slot section, and the other two elastic expansion strips 302 are inserted in parallel in the two vertical slot sections respectively; Figure 7 As shown, the cross-sectional shape of the elastic telescopic strip 302 is set to be U-shaped, and is composed of a first strip plate and two second strip plates. The plate surface of the first strip plate and the plate surface of the second strip plate are arranged in parallel, and the two second strip plates are arranged vertically and symmetrically on the same plate surface of the first strip plate, and are respectively located at the ends of the first strip plate, and the two second strip plates are both arranged to be a wavy structure; the guide rod 303 is set to be a round rod structure, and is installed in parallel at a relatively concave position on the second strip plate; when there are three relatively concave positions on the second strip plate, the number of guide rods 303 is correspondingly set to six, and the six guide rods 303 are divided into two groups, and the three guide rods 303 in the same group are arranged in parallel on the same second strip plate, and are arranged at intervals along the groove depth direction of the first belt groove 1031.

[0044] In a further embodiment, the guide portion 301 is configured to include three guide rail groups, each guide rail group includes two pairs of guide rails 3011, the two pairs of guide rails 3011 of the same guide rail group extend along the groove depth direction of the first belt groove 1031, and the two guide rails 3011 of the same pair are respectively arranged at both ends of the same elastic telescopic strip 302; the two ends of the guide rod 303 are respectively slidably inserted into the two guide rails 3011 of the same pair.

[0045] Specifically in this embodiment, Figure 5 and Figure 6 , one of the guide rail groups is inserted in the cross beam, and the two pairs of guide rails 3011 of the guide rail group are arranged at intervals along the length direction of the first belt groove 1031, and the two guide rails 3011 of the same pair are respectively arranged at the left and right ends of the same elastic telescopic strip 302, and the guide rails 3011 extend along the groove depth direction of the first belt groove 1031, so that the guide rod 303 can only slide along the groove depth direction of the first belt groove 1031; the other two guide rail groups are respectively inserted in the two vertical beams, and the two pairs of guide rails 3011 of any guide rail group are arranged at intervals along the length direction of the first belt groove 1031, and the two guide rails 3011 of the same pair are respectively arranged at the upper and lower ends of the same elastic telescopic strip 302, and the guide rails 3011 extend along the groove depth direction of the first belt groove 1031, so that the guide rod 303 can only slide along the groove depth direction of the first belt groove 1031.

[0046] During use, when the strapping strap 5 contracts, the strapping strap 5 moves outward along the groove depth direction of the first belt groove 1031, and is clamped by the guide rods 303 on both sides under the action of the force and moves toward the strapping station 102, so that the strapping strap 5 can be restricted and avoid being in a completely free state; in the process of the strapping strap 5 driving the innermost pair of guide rods 303 to move, the guide rods 303, on the one hand, slide along the groove depth direction of the first belt groove 1031 under the guidance of the guide rail 3011, and on the other hand, gradually stretch the second strip plate.

[0047] When the innermost pair of guide rods 303 are close to the middle pair of guide rods 303, the strapping belt 5 is automatically switched to the middle pair of guide rods 303 under the action of contraction. In the process of the strapping belt 5 driving the middle pair of guide rods 303 to move, the guide rods 303, on the one hand, slide along the extension direction perpendicular to the elastic expansion strip 302 under the action of the guide portion 301, and on the other hand, gradually stretch the second strip plate; when the middle pair of guide rods 303 are close to the outermost pair of guide rails 3011, the strapping belt 5 is automatically switched to the outermost pair of guide rails 3011 under the action of contraction. In the process of the strapping belt 5 driving the outermost pair of guide rods 303 to move, the guide rods 303, on the one hand, slide along the groove depth direction of the first belt groove 1031 under the guidance of the guide rails 3011, and on the other hand, gradually stretch the second strip plate, so that the strapping belt 5 can be clamped and transferred to the connection between the guide portion 2 and the gantry 103.

[0048] When the binding belt 5 is separated from the elastic stretch strip 302, the elastic stretch strip 302 is automatically reset under the action of elasticity.

[0049] In a further embodiment, the acting force may be configured as a magnetic force.

[0050] Specifically in this embodiment, the force generating part can be set as a magnetic material, and is respectively arranged on the strapping belt 5 and the guide rod 303, so that a magnetic connection can be generated between the strapping belt 5 and the guide rod 303.

[0051] During use, when the strapping belt 5 contracts, the strapping belt 5 moves outward along the groove depth direction of the first belt groove 1031, and is clamped by the guide rods 303 on both sides through magnetic force to move toward the strapping station 102, so that the strapping belt 5 can be clamped and transferred to the connection between the guide part 2 and the gantry 103.

[0052] In other embodiments, the acting force may also be set as suction force.

[0053] Specifically in this embodiment, the force generating part can be set as an air pump and a plurality of small holes, the guide rod 303 is set as a hollow structure, and the plurality of small holes are opened on the circumferential side wall of the guide rod 303 and arranged at intervals along the extension direction of the guide rod 303.

[0054] During use, the vacuum pump is started and the air inside the first belt groove 1031 is sucked through the small hole; when the strapping belt 5 contracts, the strapping belt 5 moves outward along the groove depth direction of the first belt groove 1031, and is clamped by the guide rods 303 on both sides by suction and moves toward the strapping station 102, so that the strapping belt 5 can be clamped and transferred to the connection between the guide part 2 and the gantry 103.

[0055] In other embodiments, the material of the strapping belt 5 can be nylon.

[0056] Specifically in this embodiment, nylon has excellent tensile strength and can withstand large pulling forces without breaking, which makes it possible to firmly bundle various items, whether they are light documents and parcels, or heavier industrial parts, building materials, etc., to ensure the stability of the bundling, thereby helping to reduce the risk of loose items during transportation and storage.

[0057] In other embodiments, the material of the strapping belt 5 may also be steel or PET polyester.

[0058] Specifically in this embodiment, when the material of the strapping strap 5 is steel, the steel material gives the strapping strap 5 a higher strength, which is suitable for bundling super-heavy goods, such as large mechanical parts, bundles of steel, heavy industrial equipment, etc., and can ensure that it remains in a tight state under extreme stress conditions; when the material of the strapping strap 5 is PET polyester, the PET polyester material makes the strapping strap 5 have good flexibility and rigidity, and it is not easy to break under complex stress conditions such as bending and torsion. It is suitable for bundling objects with irregular shapes that need to be bundled at multiple angles, such as furniture, bicycles, etc.

[0059] In other embodiments, the strapping machine body 1 can be configured to include a chassis, and a second belt groove 104 is opened on the top of the chassis, the second belt groove 104 is located directly below the gantry 103, and is arranged parallel to the crossbeam, the second belt groove 104 and the first belt groove 1031 cooperate to form a rectangular strapping area, a first conveying device and a third conveying device are arranged in the second belt groove 104, and a second conveying device is arranged in the first belt groove 1031; the third conveying device is also provided with a clamping device for clamping the end of the strapping belt 5 at one end facing the first conveying device; and a tensioning mechanism and a sealing mechanism are also inserted in the chassis, wherein the tensioning mechanism is used to tighten the strapping belt 5; the sealing mechanism can move between the first conveying device and the third conveying device in the vertical direction, and is used to hot-melt seal the end of the strapping belt 5.

[0060] It is understandable that since the specific structure of the strapping machine body 1 is prior art, it will not be described in detail; for details, reference may be made to the specific structure of the packaging machine disclosed in Chinese patent application CN117022748A.

[0061] During use, the parts of the steel furniture are first placed at the bundling station 102, and then the strapping belt 5 is fed from one end of the first conveying device, passed through the second conveying device, and finally sent out by the third conveying device. After being sent out, one end of the strapping belt 5 is clamped by the clamping device, and the other end of the strapping belt 5 is tightened by the tensioning mechanism, and then the end of the strapping belt 5 is hot-melt sealed by the sealing mechanism, so that the strapping belt 5 is tied to the parts of the steel furniture.

[0062] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
